Original flathead water pumps have always suffered from unreliable bronze bushings and carbon seals. They almost always leaked and even Ford manuals warned mechanics not to tighten fan belts too tight. The excess slack allowed belts to slip and lose contact with the generator and water pump pulleys, causing more cooling and power problems.

Speedways completely new water pumps feature severe-duty roller and ball bearings, close tolerances and modular impellers to provide maximum flow and reduce cavitation. They also have modern ceramic seals on a heavy duty 3/4" shaft, making the assembly exceptionally strong and more efficient.

Note: This water pump is for 1949-1953 engines in 1948-1952 pickups or 1932-1948 cars.

Speedway's adjustable water pump is tried, tested and true. It has great flow, superior quality and standard features that are typically only available on water pumps costing twice as much. State-of-the-art aluminum casting and a precision impeller provide equal flow to both cylinder banks. If you're using a cog belt on your race car, this is the pump you want since it's adjustable. The 1/2" mount holes in this pump are larger than normal, allowing it to be moved up or down slightly to help with belt tension.

Adjustable mounting holes

High flow and pressure rates

Adjustable cam stop

Extra-thick fan hub

3/4" inch heavy duty bearing

Pressed-fit and set-screw-retained fan hub

Large-diameter shaft and reinforced housing make it ideal for oval-track applications

This super heavy duty race water pump features additional casting designs for more strength and reinforcement, plus a 3/4" fan pilot shaft and super duty bearing. It has1/2" NPT threaded outlets on both the top and side, plus a 3/16" steel rear plate. It weighs 7-3/4 lbs.

Speedway Short Aluminum water pumps flow 35 gallons per minute at 4,000 RPM, with minimal cavitation and proportionally increased flow rates at 5,000 RPM and above. Equalized water flow distribution and pressure-balanced water passages minimize internal engine hot-spots making these pumps an excellent alternative for not only light duty racing, but also marine, trucks, towing, and motorhome applications. Cruisers and hot rodders will appreciate the improved cooling at low speeds.

"Short" style pumps came on all factory small block V8s from 1955 to 1968. However, this pump will fit all S/B Chevys up to 1985.

Uses new, OEM cast iron castings precision machined and assembled by Stewart Components to their exacting standards. They feature higher flow and pressure for better cooling. They have a 3/4" bearing and 5/8" shaft.

Castings are internally modified for performance and reliability

Compatible with stock lines and brackets

Precision ground hub for perfect pully alignment

Equal flow to left and right cylinder heads

Recommended for stock, OEM, or mild performance applications

One year warranty

Note: If using a mechanical fan, we suggest using a 3/4" shaft water pump.
